Hi Linus,
Please pull powerpc updates for 5.2.
Slightly delayed due to the issue with printk() calling probe_kernel_read()
interacting with our new user access prevention stuff, but all fixed now.
The only out-of-area changes are the addition of a cpuhp_state, small additions
to Documentation and MAINTAINERS updates.
No conflicts that I'm aware of.
cheers

powerpc/64s: Use early_mmu_has_feature() in set_kuap() (2019-05-09 14:28:56 +1000)
- ------------------------------------------------------------------
powerpc updates for 5.2
Highlights:
- Support for Kernel Userspace Access/Execution Prevention (like
SMAP/SMEP/PAN/PXN) on some 64-bit and 32-bit CPUs. This prevents the kernel
from accidentally accessing userspace outside copy_to/from_user(), or
ever executing userspace.
- KASAN support on 32-bit.
- Rework of where we map the kernel, vmalloc, etc. on 64-bit hash to use the
same address ranges we use with the Radix MMU.
- A rewrite into C of large parts of our idle handling code for 64-bit Book3S
(ie. power8 & power9).
- A fast path entry for syscalls on 32-bit CPUs, for a 12-17% speedup in the
null_syscall benchmark.
- On 64-bit bare metal we have support for recovering from errors with the time
base (our clocksource), however if that fails currently we hang in __delay()
and never crash. We now have support for detecting that case and short
circuiting __delay() so we at least panic() and reboot.
- Add support for optionally enabling the DAWR on Power9, which had to be
disabled by default due to a hardware erratum. This has the effect of
enabling hardware breakpoints for GDB, the downside is a badly behaved
program could crash the machine by pointing the DAWR at cache inhibited
memory. This is opt-in obviously.
- xmon, our crash handler, gets support for a read only mode where operations
that could change memory or otherwise disturb the system are disabled.
Plus many clean-ups, reworks and minor fixes etc.
